Description:
------------
This bug was reported and fixed in 2002 i think, but in PHP 5.1.1 + Apache 2 i'm getting this message

"Warning: ob_start() [ref.outcontrol]: output handler 'ob_gzhandler' cannot be used twice"

In many of the pages of PHPNuke framework

I'm sure about the existence of output_handler = and zlib.output_compression = Off directives in the PHP configuration file.

I'm not using CGI, i'm using the DLL for Apache component

Reproduce code:
---------------
For example in the \html\includes\page_header.php file in PHPNuke framework

The lines are as follows
if ( extension_loaded('zlib') )
{
   ob_start('ob_gzhandler');
}


Actual result:
--------------
Warning: ob_start() [ref.outcontrol]: output handler 'ob_gzhandler' cannot be used twice in C:\Program Files\Apache Group\Apache2\htdocs\portal\html\includes\page_header.php on line 58

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Somewhere in your code or configuration the output handler ob_gzhandler is already being set. The error itself is perfectly correct in this case.
